Cet article est une revue de la littérature où le temps passé dans un état est une variable aléatoire issue d’un mélange continu de distributions. Elle s’est constituée à partir de l’estimation de fonctions de hasards et de méthodes d’approximations d’intégrales. Nous...

In this paper, we consider American option contracts when the underlying asset has stochastic dividends and stochastic volatility. We provide a full discussion of the theoretical foundations of American option valuation and exercise boundaries. We show how they depend on the various sources of...

The paper contributes to the literature on the convergence of financial systems in the euro area by estimating household credit demand in individual countries. Using the ARDL framework advocated notably by Pesaran et al. (1999), the paper provides evidence on the convergence of long run credit...

Deux indicateurs sont proposés, le premier (IPCA, indicateur probabiliste du cycle d’accélération) visant à détecter les phases de ralentissement et d’accélération de l’ensemble de l’activité économique, le second (IPRI, indicateur probabiliste de récession industrielle) les...

This paper proposes a new empirical representation of inflation expectations errors in a Space-State Markov-Switching framework. We explicitly identify the dynamics of inflation expectation errors using the expectations augmented Markov-Switching Phillips curve as a measurement equation. In this...

This paper proposes two new coincident probabilistic cyclical indicators developed by the Bank of France in order to follow, on a monthly basis, the French economic activity. The first one is an indicator which aims at detecting the turning points of the acceleration cycle while the second one...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

In a Constant Proportion Portfolio Insurance (CPPI) framework, a constant risk exposure is defined by the multiple of the strategy. This article proposes an alternative conditional multiple estimation model, which is based on an autoregressive quantile regression dynamic approach. We estimate...

We consider the problem of testing whether the observations X1, · · ·, Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed:...
